8 Claims. (CI. 20-12) My invention relates to a new and useful improvement in a window construction in which the sash is slidably mounted in a window frame. In this type of construction there are usually two sashes both slidably mounted and the invention relates particularly to the slides which are supported by the window frame and which engage the sashes in their sliding movement.

It is an object of the present invention to provide a window construction of such a nature that the frame may be constructed of standard size and inserted in a window opening formed in the building and so arranged that the sashes may be mounted in the frame and the slides, which engage the sashes, adjusted to various positions, thus accommodating the structure to variations which may occur in the frame itself. The window sashes which are mounted in the frame may vary in width and the present construction affords the means for adjusting to accommodate these various widths within certain limits. Moreover, the window frame may become warped or distorted, and the present construction provides a means for compensating for such warping or distorting.

Another object of the invention is the provision of a construction in which the slidable sashes will always be engaged by a slide bearing against the same with the proper and pre-determined degree of pressure.

Another object of the invention is the provision of a threaded member for moving the slide inwardly and outwardly from the sash rail and maintaining a constant pressure on the sash rail regardless of the distance of the slide rail from the frame.

Another object of the invention is the provision in a window construction of this type of a slide rail which is inoveably mounted relatively to the supporting frame, and which may be positively moved inwardly and outwardly from the supporting frame and at the same time pressed outwardly therefrom under a constant spring pressure.

Other objects will appear hereinafter.

It is recognized that various modifications and changes may be made in the detail of structure illustrated without departing from the invention, and it is intended that the present embodiment shown herein shall be considered but the preferred form.

Forming a part of this specification are drawings in which,

As shown in Fig. 1 the invention is used with a window frame embodying the upright rails l5 and I 6, the top rails I8 and the bottom rail or sill ii], which are adapted for mounting in an opening [1 formed in a wall Ila. Slidable in this window frame are the sashes generally indicated as 29 and EL. The sash 20 embodies the upper rail 22, the lower rail 23 and the oppositely disposed side rails 24 and 25. The bottom sash. 2i embodies the upper rail 26, the lower rail 27 and the oppositely disposed side rails 28 and 29. Mounted on the inner face of the frame rails l5 and I6 is a pair of parallel slide rails which serve to engage the opposed face of the side rails in the sash.

These slide rails at opposite sides of the window frame are generally constructed the same and comprise a plate 30', formed preferably from metal, having the outwardly pressed troughshaped portion 3|, and this plate 30 has the angularly turned flanges 32 and the feet or flanges 33 as clearly shown in Fig. 4. His trough-shaped portion serves as a guide rib which engages in the groove 35 formed in the opposed face of the sash rail.

On one side of the window frame, as clearly shown in Fig. 3, the slide rail is secured in fixed position relatively to the side rail l5 of the window frame by means of the screws or nails 34 which are driven through the central rib-forming portion 3|, so that this slide rail is in fixed position relatively to the rail l5.

On the opposite side the slide rail may move inwardly and outwardly from the side rail of the frame. As clearly shown in Fig. 4 the rib or trough-shaped portion 33 is provided with an opening 38 in which seat the head 3! carried by the screw 38. This head 3? is slightly larger than the opening 36 so that it cannot pass through this opening 38. The rib or troughshaped portion 3: engages in the longitudinal groove 35 formed in the window sash rail. Positioned on the screw 38 is the cup-shaped engagement member or collar 39 which is placed on the screw 33 and the screw 38 is then upset to provide the collar 4:? so that the head 3'! is held securely against the rib 3| at one side, and the collar 39 is held securely against the rib ill at the other side.

The screw 38 projects through an opening 44 formed in the metal plate 42 which is secured by the screw 43 to the face of the frame rail l6. Formed in this frame rail I is a recess 4| in which is positioned a housing 45. This housing 45 is provided at one end with the outwardly struck tongue 46 which projects through the slits 41 formed in the plate 42 and which are then upset to securely attach the housing 45 to the plate 42. Positioned in this housing 45 is a spring 48 which bears at one end against the bottom of the housing 45 which is positioned in the pocket 4|. The opposite end of the spring 49 bears against a nut 48 having the central threaded opening formed therein, and this nut 48 is larger than the opening 44 formed in the plate 42 so that it is held centered relatively to the housing and is adapted to receive the screw 38.

When assembled, the parts would be as shown in the drawings and particularly brought out in Fig. 4 and in Fig. 3. Should it be desired to remove the window sash from the frame it would be but necessary to uncover the head 31 of the screw and thread the same inwardly until te rib or trough-shaped portion 3| disengages from the groove 35, thereupon the side of the window sash could be swung outwardly or inwardly as desired.

After the window has been placed in position the screw 38 may be rotated to move the slide rail toward the side rail of the sash and away from the rail 16 of the frame until the proper engagement of the slide rail with the sash rail has been effected. In this movement the slide rail will be positively moved outwardly from the rail 18 because of the threading of the member 38 in the nut 48. This nut 48 will be held against rotation because it is positioned in the housing 45 which is rectangular in the cross section. The nut 48 will also be prevented from sliding or moving to the left of Fig. 4 by virtue of the pressure of the spring 49 which bears at one end against the nut 48. The inward movement of the slide rail is effected by turning the screw 38 in the opposite direction and as this screw 38 turns in the opposite direction the nut 48 would of course bear against the inner face of the plate 42. Thus it will appear that the nut 48 follows in engagement with the face of the plate 42.

The sashes which are to be mounted in the window frame illustrated are frequently of various widths and the present construction is so arranged and constructed that variations within the limits of the adjusting feature may be compensated for. It also frequently happens that the window frame itself becomes distorted or twisted and this distortion or twisting may also be compensated for within the limits of the adjusting feature.

In Fig. 4 I have shown a slightly exaggerated illustration with the slide rail positioned considerable distance of the rail I6, but this distance may be achieved if desired. In some constructions the opposed face of the sash rail in which the groove 35 is formed might be closer to or farther away from the face of the rail 13 and in such a case the screw 38 would move the slide rail to the proper distance, either inwardly or outwardly from the rail Hi. It has also been noted that after the sash has been installed it may swell due to moisture and it may have some tendency to bind in the guide rail or slide rail. This is avoided by virtue of the fact that the slide rail which is held in position by the screw 38 may be moved inwardly toward the rail I6 against the compression of the spring 49 so that there thus is an automatic compensation for any swelling or spreading of the sash itself.

In the normal operations the slide rail would be moved outwardly until it snugly engages in position with the trough or rib 3| in the groove 35, under such conditions there is no pressure exerted by the spring 49 on the slide rail. The spring 49 would exert a thrust on the slide rail only when the slide rail is moved bodily toward the rail I5 carrying with it the screw 38 so that the normal frictional engagement of the slide rail with the face of the sash rail is determined, not by the pressure of the spring, but by the adjustment of the screw 38. Should this frictional engagement be such that the screw 38 would have a tendency to move the nut 48 to the left, the spring 49 would then be under compression and it would exert a pressure of the slide rail against the rail of the sash. In the normal operation of the construction the screw 38 would be so adjusted that the nut 48 would be spaced inwardly slightly from the inner face of the plate 42 with the spring 49 exerting a slight pressure of the slide rail against the sash thus maintaining a tight frictional contact, but a contact which is constant. This constant pressure may be obtained against the slide rail regardless as to the position of the slide rail inwardly or outwardly of the frame rail l6. Consequently, it becomes possible to adjust the slide rail inwardly or outwardly of the frame rail I8 to various positions and yet maintain a constantly determined pressure of this slide rail against the opposed face of 2 the sash rail.

A construction of this type has proven most efficieut and by virtue of having the rib or trough 3i engaging in the groove 35 a sealing against passage of draughts through the window around the edges of the rails of the sash is prevented.

A spring counter-weight 62 is mounted on the window frame in which is wound a strip 53 of metal which is attached to a side rail of the sash, these members 62 being provided for each of th sashes. This takes the place of the ordinary sash cord used in the windows of common construction. The detail of the member 62 is not shown as it is an article which is well known and commonly used.
